2)Suppose the local shop makes dining room tables in three shapes and in three different finishes. Their production of the last six months is summarized in the following table: 



Suppose one table is selected at random, Find the following:
A) P(the table is oval) = 177/400 B) P(the table is pine or rectangular) = 101+47+26/400 = 177/400 C) P(the table is round and mahogany) = 43/400 D) P(the table is oak | it is round) = 52/129 E)P(the table is oval | it is mahogany) = 62/152.
3)A coordinator will select 7 songs from a list of 13 songs to compose an event's musical entertainment lineup. How many different lineups are possible?A: 13vPv7 = 8648640
6) A box contains 16 white marbles and 12 green marbles. If two are drawn without replacement, what is the probability that they are both green? - 12/28 * 11/27 = 132/756.
7) The local restaurant is offering a dinner special that includes an appetizer, an entree, and a dessert. If there are 5 different appetizers to choose from, 11 different entrees, and 4 different desserts, how many different specials are possible? - 5114 = 220
